1. IMO, he told you the truth; and, I experienced this first hand since in the past one of my Mac computers was infected by all sorts of viruses/trojans ---- and, all at the same time (while I was staying at a motel that had just recently installed a broad-band/high-speed internet connection). Only thing that helped me get rid of them was Norton Antivirus software for Mac & several hours (by phone) of collaboration with some Norton engineers in India. Took days, but I finally cleared my Mac of all infection; and, have been using NAV for Mac software ever since.

I really must remember to ignore everything I read on the Internet on April 1st
